Cheap and works!
I have a 2014 Mazda CX-5. They have history of having headlight ballast issues. My passenger side headlight was not working, low or high beam. I ordered these cheap ones in the case I was having a ballast system issue. It turned out to just be the bulb but for the price they are bright and white to where they actually match the color of my LED fog lights. Excellent value and will eventually order some brighter ones in the long run, but I am completely happy with these for now.

A great replacement bulb for my 2011 Lexus GS350
It fits my 2011 Lexus GS350 perfectly. These bulbs are the fraction of the cost. The bulbs come with white glove for installation. I highly recommend to buy them!

Very bad life span. Only lasted 3 months.
I got these bulbs in August 2025 by January 2026 they burst and went out. I'd reccomend looking somewhere else and save your money.

Works perfectly on my 2011 CR-Z
The low beam on the passenger's side of my car blew out, so I had to get these. They come nicely packaged in a box with surrounding styrofoam and a plastic projector around the bulb. I had to watch a YouTube video to see how to replace the headlight, and it turned out to be pretty easy. The color is noticeably whiter than the OEM version, but that doesn't really bother me.

The bulb on the right is what was replaced with the new product. It's kind of hard to tell but it is definitely brighter than the stock OEM one on the left; however, that is to say the OEM one is 10+ years old. This is definitely a bang for your buck, really easy to install, the bulbs come in a safety protection casing, which is then fitted into Styrofoam. It also came with special gloves for the installation, which is very generous! Will update in a month if it still works and/or of the brightness of the bulb.
